Answer:
Step-by-step explanation:
One unit of length on the plan represents some number of same units of length on the ground,such as 1/1000,etc.
This Ratio of map distance to the corresponding ground distance is independent of units of measurement and is called representative fraction (R.F.).
The representative fraction can be very easily found for a given engineer’s scale.
If the scale is
R.F.=1/200000
=1/2x 1000x100
1cm=2000m
The scale of a map is given as= 1:200000
Two cities are 3 cm apart on the map.
=3x 2000
=6000m
=6000/1000 Km
=6Km
